to prevented who are in front of the vehicle;

they are however not constructed so that they can prevent the turningover of collid-r ing vehicles.

According to the invention this inconveni? ence is avoided by mountingon lthe outer one of movable plates spiral springs ot steel taperingtowards the -front end. On'the conical endY of each steel spring arubber buffer is mounted, so that persons struck by the guard are notinjured nor can they get under Y the vehicle, as Ythe guard extends downwa rds ahnostto the road. I

At' a collision of twojvehicles fitted with' such guards the rubberbulfers and the coni'-` 135 cal steel springs engage between each other,so that tumbling over of the vehicles or oi' one of said vehicles isprevented, as the vehicles are comparatively rigidly connected with eachother by thev springs inserted between each other.

To detach this connection, either a wooden* hammer is used :forhammering on the springs, or theextreme'platesare removed from thevehicles and the springs singly liberated from therear side of theplates.

Guards 'of this type are suitable for vehices of any kind, like railwaycars, vtramway cars, autobusses or motor-cars. The guards can be builtin such a manner that Y '40 they scarcely impair the appearance of thevehicle. `By the use of such guards the` safety of the passengers atcollisions is much is prevented.
